SILAS II. RAYMOND, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO T. STEWARTWHITE AND THOMAS FRIANT, OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 491,954, dated February14, 1893.

Application filed April 12, 1892.

.To aZZ whom it may concern:

Be it known that I, SILAS H. RAYMOND, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State ofMichigan,have invented certain new and useful Improvements inCarpet-Sweepers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in carpet sweepers, and its objectis to provide the same with certain new and useful features, hereinaftermore fully described and particularly pointed out in the claims,reference being had to the accompanying drawings in which; I

Figure 1 is a plan view of a device embodying my invention with portionsof the same broken away to show the internal construction. Fig. 2 an endview of the same with the outer case in section, on the line 2-2- ofFig. 1, and an end elevation of the inner frame and parts attached; and,Fig. 3 a detail of the 'ournal box for the brush shaft.

' Like letters refer to like parts in all of the figures.

A represents the outer case, which consists of a plain shell, having thebail socket A attached; within this case is a detachable frame B, havingattached the dust pans G. A rod D passes through inclined slottedopenings N in the end walls of said frame, said rod has driving wheels Ejournaled upon its respective ends, which Wheels engage the fioor andsupport the forward side of the device, and also engage the drivingpulleys F on the outer ends of the brush shaft G, which shaft is journaled in movable bearings M, which bearings engage inclined slottedopenings N in the end walls of the frame, said bearings have upwardlyextended arms L attached, which are provided with eyes H, which engagethe free ends of springs J, said springs being attached to the end wallsof the frame 13, and adapted to force the bearings M toward the upperends of the openings N, said openings N and N are inclined toward eachother, at their upper ends, at an angle of about forty-five degrees,

so that as the rod moves up the inclined open- Serial No. 428,901. (Nomodel.)

ing N ,by pressure on the case applied through the bail A the springs Jyield and allow the bearings M to move downward in the openings N, in adirection substantially at right angles to the line of motion of the rodD, thus lowering the brush relatively to the case, and at the same timelowering the case relatively to the floor, the result being that thepansand case are lowered toward the floor less than is a the brush,which is the most desirable movement of these parts.

At each end of the frame is a strip I which engages the inner surface ofthe case and guides the frame to place, where said frame is secured atthe front side by a knob'P engaging a depression Q in the inner surfaceof the case, and at the rear by the spring catch R, formed by the freeend of the shoe R, which shoe is attached to the frame at its forwardend and is turned in a substantially in- Volute curve downward andrearward, engaging the floor and supporting the rear of the device, andcontinuing thence upward and forward terminating adjacent to the outersurface of the case, form-ing said catch R ,which engages a suitablehook T attached to said case. Attached to this shoe R and near said freeend is a ring S, within which the finger is inserted to release said endfrom the hook T, whereupon the frame B may be removed from the case, theshoe R thus serves to support the device on the floor; to form a catchto secure the frame in place, and a handle to manipulate the same whendetached from the case.

What I claim is- 1. In a carpet sweeper, in combination with drivingwheels, and a brush shaft having pulleys engaging said wheels, bearingsfor said wheels and shaft, supported in oppositely inclined slottedopenings, and movable therein, substantially as described.

2. In a carpet sweeper, driving wheels journaled on diagonally movablebearings, a brush shaft having pulleys engaging said driving wheels,diagonally movable bearings for said brush shaft, and springs attachedto said brush shaft bearings, substantially as described.

3. In a carpet sweeper in combination with an outer case and an innerdetachable frame,

a depression in the inner surface of the case, a knob on the frameengaging said depression, a shoe attached to the opposite side of theframe, engaging the floor and supporting the structure and turned in aninvolute curve, and engaging a hook on the case, substantially asdescribed.

4. In a carpet sweeper, in combination with a case, and a removableframe therein, a shoe attached to the frame and extended rearward andupward in a substantially involute curve, and engaging a hook 011 saidcase, forming a combined shoe, handle, and catch, substantially asdescribed.

5. In a carpet sweeper, a case, a detachable frame in said case, a rodpassing through diagonal slotted openings in the frame, driving SILASII. RAYMOND. itnesses:
